GALL-REGISTEEING ATTACHLWENT FOR TELEPHONES.

Application filed June 11, 1919.

i To all w/ima it may concur-a Be it known that l, ABRAHAM REUBEDP s'ronn, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful improvements in Call-ite 'istering Attachments for Telephones, of which the following is aspeoilication, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to call registering devices for telephones, and the object thereof is to provide an improved device of this class wliich is in practice, attached to the transmitter head of the telephone and which controls the action of the transmitter; a further object being to provide a call registering device for the transmitter of telephones which is designed to prevent over charges, and inischarges, and to keep a true and accurate account of all calls for which the user of the telephone is liable, and which is also designed, as abovestated, to be attached to and used in connection with the head of the transmitter of a telephone and which forms a part thereof when in use;

further object being to provide an attach ment for telephones of the class specified which will register all outgoing calls made by the user of the telephone and which will cancel all outgoing calls not received by the party or parties on'whom they are made, and which not only controls the operation of the transmitter but may be operated for the purpose of registering outgoing calls when the ran'mitter is used and before using said lransini rer for making such calls; a further object being to'provide an attachment for telephones of the class siieciiied which is.

adapted to be connected with the head of the transmitter by simply detaching the mouthpiece from said head and securing said attachment in connection with said head after which the mouthpiece is applied to the attachment; and with these and other objects in view the invention consists in a telephone attachment of the class specified, constructed and operating as hereinafter described and claimed.

This invention is an improvement on that described and claimed in U. S. Letters Patent No. l,287,099 granted to me December 10, 19155, and a further object of said invention is to simplify the construction described Specification of Letters Patent.

In the drawing forming part of this specification I have shown at a, Fig. 1, an ordinary desk telephone, the standard of which 13 provided with the usual transmitter head I body or casing (12, and a receiver supporting and ready for use.

plate a of the transmitter head, and said cap plate 12 of the attachment is provided with a central screw-threaded aperture 1),

and when using my improvement the mouthpiece a is detached from the transmitter head and the attachment is connected with the cap plate a of the transmitter head and the mouthpiece a is connected with the cap plate 6 of the attachment, all as clearly shown in Fig. 5.

Mounted in the cylindrical body portion 12 are front and back frames 0 and d, which are secured together by a plurality of screws 0 as shown in Fig. 3. The back frame (Z is provided with a central aperture d and at one side of said frame is a forwardly directed sleeve portion (5 and at the other side is a rearwardly directed and shorter sleeve portion d. Mounted on the sleeve portion dof the frame (Z is an annular collar 6 having a central aperture 0 and said collar is threaded as shown at c to engage a threaded aperture a of the cap plate a, as clearly shown in Fig. 5.

The back frame (Z is provided with a raised semi-circular extension (5 which forms a seat or receiver for a registering device f as shown in Fig. 5 of the drawing and the top of the body portion is pro vided with an aperture 1) through which the top of the registering device f passes whereby the dials of said device may be seen from 'he to of the attachment .6 as indicated in Fig. 6.

The annular collar 6 is provided on the periphery thereof with an annular recess 0 and two set screws 6 are passed through the body portion 6 at the opposite sides there of into and through the corresponding sides of the back frame (1, and the inner ends 6 thereof operate in said annular recess 6 to retain the frame members 0 and d in connection with the annular collar e or these screws serve to connect or hold the attachment 1) in connection with the transmitter head a of the telephone, and, as will be understood, also permit the adjustment of the attachment 6 relatively to said" transmitter.

The front frame a is provided with an an nular portion 0 which extends around the periphery of said frame as shown in Fig. 3, and which is in line with and of the same general form as the back frame d, or is provided in the top thereof with arc-shaped portions 0*, one of which is shown in Fig. 3, and which also form a seat for the registering device as indicated in said figure.

The bottom of the frame 0 is provided with a cylindrical head 0 in which a cylindrical lock device 9 is adapted to be mounted, said lock device being threaded on its inner end as shown at g and a lock nut g is mounted thereon to hold said lock device 9 in connection with the cross head 0 as shown in Fig. 5 of the drawing.

Two ratchets h and k are secured to a sleeve cam member 0 which is rotatably mounted on the central sleeve portion (Z of the frame d, as is also a large gear if, and the gear 7L3 and ratchets h and [L2 are secured together by screws h which pass backwardly therethrough as shown in Fig. 5, and these screws also secure an annular dial k to the face of the gear h as clearly shown in said figure. The dial 71 is pro vided on its outer face with the designating characters On and Off alternately spaced around the face of said dial as shown at h in Fig. 2 ofthe drawing, and these characters operate in conjunction with an aperture 6 in the cap plate 7) as shown in Fig. 5 of the drawing, and said apertu e is preferably provided with a transparent panel b The large gear 71 which is mounted on the sleeve portion d of the frame (Z and adapted to be rotated with the ratchets IL and k is adapted to mesh with a pinion f on the shaft of the registering device 7' as shown in F ig. 5 of the drawing. Two pawls i and j are pivotally mounted in connection with slides i and f, having arc-shaped seg ments 2' and j which guide the slides i and j and permit of their movements circumferentially between the frame members 0 and d, or recesses 0 and d in the periphery thereof, as clearly shown in Fig. at of the drawing.

The slides 2' and f, or the segmerts i and 7' thereof are provided centrally with finger pieces 2" and j, which extend through and are adapted to operate in elongated apertures in the opposite side walls of the cylindrical body portion 12 as clearly shown in Figs. 3, 4 and 6 of the drawing. The inner end portions of the slides i and 7' are cut out to form flanges 2' and 7' which fit between and operate between the ratchets 72, and If, as clearly shown in Fig. 4 of the drawing, and these flanges in conjunction with the arc-shaped segments 2' and 7' serve to guide the slides i and 7' in their movement in said frames 0 and d.

The pawls i and 7' are adapted to be moved into enga ement with the ratchets h and b respectively by spring devices i and j mounted on and carried by the slides i and 7' and pawls z' and j are normally held head portions 2' and f thereof engaging rollers 21 and j mounted in connection with the back frame (5 by suitable screws 7? and j as shown in Fig. 3 of the drawing. It will be understood that when the slides i and 7 are mo red downwardly by an operator pressing the finger pieces i and j* downwardly so that the head portions i and 7' of the pawls and 7' will be disengaged from the rollers 2' and j the springs i and 7' will force said pawls into engagement with the ratchets h and 7L2, and the slides 2' and 7' will automatically be returned to their normal position as shown in Fig. 3 of the drawing by suitable springs 2' and-3' The forwardly directed sleeve portion cl of the frame (5 is provided centrally of thetop thereof with a longitudinal boss (Z and centrally of the bottom thereof with a similar but shorter boss (i and a spring arm is secured at one end to the boss (Z5 by a screw 72 and secured to or mountedon the free end portion of the arm is is an inwardly directed pin 70 the inner end of which is provided with a plug is, the face of which is provided with a fibrous or similar flexible or non-metallic cushion 79 and the plug 70 is adjustably mounted in connection with the pin it as shown at is.

The free end of the spring arm 70 is made V-shaped in form as shown at is in Fig. 8 of the drawing, and is adapted to operate in connection with the cam face a of the sleeve cam member 0 as illustrated in Figs. 5 and 8 of the drawing. The cam face 76 of said member 0 is provided with alternately arranged raised portions 7s and recessed portions k centrally of each of which are formed grooves 70 in which the V-shaped end 70 of the spring arm is is adapted to operate. The raised andrecessed portions k and 70 serve to move or control the position of the pin of the plug 70 in relation to the diaphragm a. In other words when the V-shaped portion 70 of the spring arm 7c is on one of the raised portions 70 of the cam memberc the plug is will be held out of en agement with the diaphragm a and again moved into engagementtherewith when the V-shaped portion 70 is in engagement with a recessed portion 70 on said cam member.

The lock device 9 extends through an aperture 6 in the central bottom portion of the cylindrical body portion 6 and is operated by a suitable key 9 illustrated in Fig. l of the drawing. The manipulation of the lock by the key 91* rotate's'two disks g7 and n on the inner end portion of the lock. The disk carries 'a projecting V- shaped pin g which is adapted to operate in connection with the ratchet h, as shown in Figs. and 5 of the drawing to lock the attachment against use until the key, has been inserted into the lock g to rotate the disks g and g to move the pin 9 out of engagement with the ratchet it. The disk 9 operates to control the rotary movement of the tumblers and lock cylinder as in other locks of this class.

The operation of my improved telephone attachment will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following statement. In the normal position of the attachment, the lock deaice g, or the pin 9'' thereof, is in engagement with the ratchet h, or a tooth thereof, thus preventing the rotation of said ratchet by the pawl i, and by inserting a suitable key into the lock device and rotating the same, the pin may be moved baekwardly out of engagement with the ratchet I72, thus permitting the use of the attachment. In this posiion of the parts, the plug 76 is normally bean ing on the diaphragm a, and a character Off on the dial 7f appears in the aperture t in the front plate 5 of the attachment as shown in Fig. 1 of the drawing, and if a party desires to make a call, the finger piece 2' is first depressed which operation brings the pawl i into engagement with the ratchet 7L and rotates said ratchet one step, or one tooth, and correspondingly rotates the gear 1 1 to move character 011 on the dial into alinement with the aperture 6, and this operation also rotates the pinion f to move one of the dials on the registering device, one half of a complete movement or I operation thereof. The above operation also rotates the cam member 0 and brings the spring finger 76, or the ll-shaped end portion 76 thereof into engagement with projecting portion 70 on the cam face 73 which holds the plug is out of engagement with the diaphragm a and permits the use of the transmitter of the telephone. The

receiver may then be removed from the receiver arm and the desired number called in the usual manner.

If the party making the call as above set out receives an answer, he again moves the finger piece i downwardly by hand and this operation again rotates the ratchet h, cam member gear 713, pinion f and dial it to again return the plug k into the position shown in Fig. 5, and'to bring a character Oil? on the dial it into alinement with the aperture 6 and to complete one operation of the registering device If after the number called for was not received, the wire being busy, or for any other reason, the desired party, or the number not received, then and in that event, the finger piece j is depressed by the hand of the operatorand this operation operates the pawl j, ratchet 7L gear 7& and pinion 7, as well as the dial If and cam member 0 to move said parts in the reversed position from that last set out, or in other words, to move the registering device backwardly to cancel the call about to be registered and to move the dial it backwardiy to bring one of the characters Off into alinement with the aperture 5 and also to return the plug into the position shown in Fig. 5 in the manner iereinbefore set out.

T he above clearly sets out the various uses of my improvement, and while I have shown one form of lock device and a method of locking the attachment against use and also other details of construction for carrying my invention into effect, it will be understood that various changes in and modification of the details of construction herein shown and described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.
